Marta Estevan is ready to leave the convent where she has been reared. Dona Luisa Artega, mother of Rafael and the young girl's guardian, arranges a marriage between the two, because she thinks that Marta's influence will rescue her son from the wild life he is leading and make a man of him. Marta rescues the American Bryton, when he is attacked by Indians, and falls in love with him. Rafael's mother sends Bryton away by telling him that the girl has entered a convent for life, and after telling Marta that Bryton had been killed on the trail she exacts a vow from the girl that she will marry her son. Marta marries Rafael. Bryton comes back after the marriage and after Marta has found out the true character of her husband. The story moves on from this point to a happy ending, but with much action of tense and strenuous nature in between. - Moving Picture World, May 15, 1920.
